IMPROVEMENT lN THE MANUFACTURE OF JEWELRY.

Specification forniing part of Letters Patent No. 150,754, dated May 12,1874; application filed March 14, 1874.

To all whom it may concern:

Be it known that I, CHARLES A. GAMWELL, of Providence, in the county ofProvidence and State of Rhode Island, have invented a new and usefulImprovement in the Manufacture of Jewelry, of which the following is aspecification In the accompanying drawing, Figure -l represents aperspective view of an ear-drop manufacturedaccording to my improvedprocess, and Fig. 2 a vertical central section of the same.

Similar letters of reference indicate correspondin g parts.

The object of my invention is to'produce neat and stylish articles ofjewelry, dressbuttons, 8vo., by imitating the gold, silver, glassbea-ds, and other fancy articles hitherto imported in such manner thatnot only the manufacture of the same is greatly cheapened, but also a,variety of ornamental and elegant art-icles of various shapes andcolors be produced. My invention consists in producing the body of thejewelry of wood, clay, horn, papiermach, or other cheap plasticmaterial, and prepa-ring the outer surface of the same by sizing, andvarnishing in bronze, gold, silver, aniline, or other colors, 'orproducing by the use of emery, fine sand, or other material, and asecond sizing, a frosted gold, silver, or other colored surface andfinished appearance of the goods. In the drawing, A represents a ballear-drop, or any other article of jewelry, to be produced according tomy process.4 I use, preferably, wood for producing the body of various'articles of jewelry, especially for Such shapes as maybe turned rapidly,though I do not confine myself to the use of the same exclusively, asthe various shapes may be pressed of clay, horn, paste compounds,metals, or other suitable material. VWood, however, recommends itself,together with paste compounds, on account of its lightness and ease ofworking the same. The surface of the article is either enameled or not,as desired.

A sizing is next put O11 for holding the bronze of various colors, orgold or silver leaf.

For producing a rough frosted surface, elnery-powder is placed evenlyover the rst sizing, and the bronze, gold, or silver leaf applied bymeans of a second sizing placed over the emery.

Varied and neat eects are thus obtained by very simple means, especiallyas by painting and varnishin the bronzed or other surfaces in anilineand other colors any desired shade may be produced.

A great number of different article of jewelry may be in this manner bemanufactured, which, in cheapness, lightness, and finish, may

successfully compete with the fancy goods and jewelryof Europeanmarkets, and surpass them in durability and ncatness in many cases.

Having thus described my invention, I claim as new and desire to secure.by Letters Patenti l. The process of producing buttons, imitationjewelry, and similar articles, and of ornamenting theirvsurfaces invarious colors, substantially in the manner as hereinbcfore set forth.`

2. As a new article of manufacture, a but ton, ear-ring, or otherarticle `of jewelry made of wood or other cheap material and providedwith a coating or coatings of size, bronze. gold or silver leaf orcolor, and a covering of emery powder or sand, in imitation of frosting,substantially as described.

3. As an improvement in the manufacture of jewelry, buttons, 85o.,articles of jewelry Vproduced with a rough surface of emery-powder inimitation of frosted surfaces, by sizing them and applying a secondsizing over the emery for ixin g the bronze, gold or silver leaf, orother color, as set forth.
